Subject: Re: FYI JBOSS - Almost as good as an exploded WAR

Exploded deployment and faster modify/test cycle will come as a side effect of the maven migration, currently in progress in the "goodbye-ant" feature branch. Anybody can try it by doing:

$ svn co http://halsvn01/svn/hal/branches/features/goodbye-ant hal $ cd hal $ mvn install

Looking at some JBOSS properties in jmx-console

Here's how to look at some JBOSS properties in the jmx-console

Note: You can change the current state of your server, but only during run time, configuration files are not updated. So, it's a nice way to look via a GUI and play a bit too.

http://haldevjbs##.hq.halw.com:8080/jmx-console/
where ## is your machine number

credentials:
admin/admin

Put jboss*:* in ObjectFilter name in upper right corner

Click on the link (search for):
name=SystemProperties,type=Service

Click on the "Invoke" button for showAll

You'll see all of the system properties

Another one to try (go back, and search)
Click on the link:
service=JNDIView

Click on the "Invoke" button for list

Another one to try:

Put jboss.system*:* in ObjectFilter name in upper right corner

Click on the link:
type=server

You'll see information about your server

Resolving conflict when merging

Today, we had a conflict when merging the jboss stabilization branch into the RC. Here are the steps I used to resolve it. The basic process was to first merge the RC into the jboss-stabilization branch, resolve the conflict and then merge the jboss-stabilization branch back into the RC:

552 svn co http://halsvn01/svn/hal/branches/features/jboss-stabilization
553 svn status
554 cd jboss-stabilization/
555 svn status
556 svn info
557 svn merge http://halsvn01/svn/hal/branches/RC/12.11-RC
558 svn status
559 svn resolve --accept=working halwebsite/com
560 svn status
561 svn commit -m "Sync jboss-stabilization branch with 12.11-RC"
562 ls
563 cd ..
564 rm -rf jboss-stabilization/
565 svn co http://halsvn01/svn/hal/branches/RC/12.11-RC
566 cd 12.11-RC/
567 svn merge --reintegrate http://halsvn01/svn/hal/branches/features/jboss-stabilization
568 svn status

Installing Meld on RH for compares

Source: meld-1.4.0.tar

Subject: Merge tool

If you would like a graphical diff tool, you can download meld-1.4.0 to your vm in the programs folder. More recent version of Meld don't work because the version of Python on the vms is too old.
